Agency in Tourism: A Narrative of Reclamation Found in the Public History of the Eastern Band of the Cherokee Indian
This thesis covers the development of the tourism industry surrounding the Eastern Band of the Cherokee Indian in Western North Carolina, specifically the evolution of the outdoor historical drama Unto These Hills written by Kermit Hunter. The chapters to follow examine the development of the production in conjunction with the broader historical context, analyze Kermit Hunterâs original script contextualizing the material and Hunterâs narrative choices, and elucidate the history and representation of one of the productionâs protagonists. All of this to demonstrate not only the misrepresentation and inaccuracy of the original production, but to discuss the productionâs role on the reservation today. As other historians have argued, the installation of the tourism economy in the 1930s-40s was exploitative and undoubtedly altered the way Americans have come to understand and interact with Cherokee history and culture, and the people themselves. It is true that the economic realities the Band was placed in were designed by those with little care for historical accuracy or for the preservation and protection of the Cherokee people. When the tribe took over the Cherokee Historical Association, the entity responsible for the production, the tribe gained control of the narrative which had defined them for over fifty years. They tried creating entirely new narratives around which to center their public facing identity. They have chosen, however, to return to a narrative which was once used to silence their voices. They have reclaimed Kermit Hunterâs Unto These Hills, reclaimed the heroic figure of Tsali, and reclaimed the agency which was stripped from them in the creation of the original production. Through its careful analysis, this thesis argues that authenticity and historical accuracy is defined by the people represented by the display of public memory, and though the story may be littered with questions and curiosities, it is the Cherokee story to tell

Relationships between compulsive exercise, quality of life, psychological distress and motivation to change in adults with anorexia nervosa
Background: For people with anorexia nervosa (AN), compulsive exercise is characterized by extreme concerns about the perceived negative consequences of stopping/reducing exercise, dysregulation of affect, and inflexible exercise routines. It is associated with increased eating disorder psychopathology and poor clinical outcome. However, its relationships with two important clinical issues, quality of life (QoL) and motivation to change, are currently unknown. This study aimed to assess the cross-sectional relationships between compulsive exercise, QoL, psychological distress (anxiety and depressive symptoms, and obsessive-compulsive traits) and motivation to change in patients with AN.
Method: A total of 78 adults with AN participated in this study, which was nested within a randomized controlled trial of psychological treatments for AN. At baseline (pre-treatment), participants completed questionnaires assessing compulsive exercise, eating disorder (ED) psychopathology, QoL, psychological distress and motivation to change.
Results: Baseline correlational analyses demonstrated a moderate positive relationship between compulsive exercise and ED psychopathology, and a weak positive relationship between compulsive exercise and psychological distress. There was a moderate negative relationship between compulsive exercise and eating disorder QoL.
Conclusions: These results indicate compulsive exercise is moderately associated with poorer QoL and weakly associated with higher distress. Targeting compulsive exercise in the treatment of anorexia nervosa may help reduce the burden of illness and improve patientsâ engagement in treatment.

Domain configurations in Co/Pd and L10-FePt nanowire arrays with perpendicular magnetic anisotropy
Perpendicular magnetic anisotropy [Co/Pd]15 and L10-FePt nanowire arrays of
period 63 nm with linewidths 38 nm and 27 nm and film thickness 27 nm and 20 nm
respectively were fabricated using a self-assembled PS-b-PDMS diblock copolymer
film as a lithographic mask. The wires are predicted to support Neel walls in
the Co/Pd and Bloch walls in the FePt. Magnetostatic interactions from nearest
neighbor nanowires promote a ground state configuration consisting of
alternating up and down magnetization in adjacent wires. This was observed over
~75% of the Co/Pd wires after ac-demagnetization but was less prevalent in the
FePt because the ratio of interaction field to switching field was much
smaller. Interactions also led to correlations in the domain wall positions in
adjacent Co/Pd nanowires. The reversal process was characterized by nucleation
of reverse domains, followed at higher fields by propagation of the domains
along the nanowires. These narrow wires provide model system for exploring
domain wall structure and dynamics in perpendicular anisotropy systems
An antisite defect mechanism for room temperature ferroelectricity in orthoferrites
Single-phase multiferroic materials that allow the coexistence of
ferroelectric and magnetic ordering above room temperature are highly
desirable, motivating an ongoing search for mechanisms for unconventional
ferroelectricity in magnetic oxides. Here, we report an antisite defect
mechanism for room temperature ferroelectricity in epitaxial thin films of
yttrium orthoferrite, YFeO3, a perovskite-structured canted antiferromagnet. A
combination of piezoresponse force microscopy, atomically resolved elemental
mapping with aberration corrected scanning transmission electron microscopy and
density functional theory calculations reveals that the presence of YFe
antisite defects facilitates a non-centrosymmetric distortion promoting
ferroelectricity. This mechanism is predicted to work analogously for other
rare earth orthoferrites, with a dependence of the polarization on the radius
of the rare earth cation. Furthermore, a vertically aligned nanocomposite
consisting of pillars of a magnetoelastic oxide CoFe2O4 embedded epitaxially in
the YFeO3 matrix exhibits both robust ferroelectricity and ferrimagnetism at
room temperature, as well as a noticeable strain-mediated magnetoelectric
coupling effect. Our work uncovers the distinctive role of antisite defects in
providing a novel mechanism for ferroelectricity in a range of magnetic
orthoferrites and further augments the functionality of this family of complex
oxides for multiferroic applications
Measurement of H<sub>2</sub>O<sub>2</sub> within living drosophila during aging using a ratiometric mass spectrometry probe targeted to the mitochondrial matrix
Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) is central to mitochondrial oxidative damage and redox signaling, but its roles are poorly understood due to the difficulty of measuring mitochondrial H<sub>2</sub>O<sub>2</sub> in vivo. Here we report a ratiometric mass spectrometry probe approach to assess mitochondrial matrix H<sub>2</sub>O<sub>2</sub> levels in vivo. The probe, MitoB, comprises a triphenylphosphonium (TPP) cation driving its accumulation within mitochondria, conjugated to an arylboronic acid that reacts with H<sub>2</sub>O<sub>2</sub> to form a phenol, MitoP. Quantifying the MitoP/MitoB ratio by liquid chromatography-tandem mass spectrometry enabled measurement of a weighted average of mitochondrial H<sub>2</sub>O<sub>2</sub> that predominantly reports on thoracic muscle mitochondria within living flies. There was an increase in mitochondrial H<sub>2</sub>O<sub>2</sub> with age in flies, which was not coordinately altered by interventions that modulated life span. Our findings provide approaches to investigate mitochondrial ROS in vivo and suggest that while an increase in overall mitochondrial H<sub>2</sub>O<sub>2</sub> correlates with aging, it may not be causative
Magnetization dynamics in optically excited nanostructured nickel films
In this work, Laser-induced magnetization dynamics of nanostructured nickel
films is investigated. The influence of the nanosize is discussed considering
the time-scale of hundreds of femtoseconds as well as the GHz regime. While no
nanosize effect is observed on the short time-scale, the excited magnetic mode
in the GHz regime can be identified by comparison with micromagnetic
simulations. The thickness dependence reveals insight on the dipole interaction
between single nickel structures. Also, transient reflectivity changes are
discussed
